Games like Splatoon don’t come around too often. It’s fresh and exciting in ways that are rarely seen. Marching to the beat of its own drum, Splatoon is bursting with style. So much so, that in a different era it would have made an excellent addition to the Dreamcast library. Yet despite everything it does right, the game also feels sparse, lacking in several basic areas.
Splatoon is all about ink. Your character--a boy or girl of your choosing--is made of it, all of the available weapons spew, squirt, or blast it, and the objective is usually to spread as much of it around as possible. The ink is what separates Splatoon from other online shooters. While many games in the genre emphasize kill count, Splatoon focuses on controlling space.

Nintendo has recently restored Wii U Mario Kart 8 and Splatoon online after five months of being offline.

Game Rant Writes "Mar10 Day is a fun yearly celebration of the Super Mario series, and Splatoon may warrant a fan-designated day of celebration in its own right."

How, exactly, did Splatoon reach heights rivalled only by Pokémon in Japan? New IPs from the House of Mario appear as often as shiny Pocket Monsters, yet typically move comparatively mediocre numbers or fall into relative obscurity behind the premium marques of Mario, Animal Crossing, Zelda, and Pokémon. Take Pikmin and ARMS, for example, which we adore but struggle to compete with the tentpole franchises when it comes to sales numbers or mainstream mindshare.
So, again, how has Splatoon risen to become one of Nintendo's most important series in Japan?
